It will crash miserably..... been there, done that ;) I can't remember which release I was downgrading to and from... but I did try to downgrade an MX10 and got the "hardware not supported" error. Went ahead anyways and poof!
Had to reinstall with USB ... thankfully it wasn't in production and I was onsite...

Am I forced to run 11.4+? Hi, Thanks for the information, it gives some answers. But what would actually happen if I try to install 10.4R8.5 with no-validate etc and "force" it to accept it, would it stop working or not, since it's the same hardware as the MX80 but with other "descriptions" it should work, but I'm unsure. Don't want to brick it. :-) //T On Thu, Mar 22, 2012 at 9:13 AM, Tima Maryin <timamar...@mail.ru> wrote: > Hi, > > > Here: > http://www.juniper.net/techpubs/en_US/junos11.2/information-products/t > opic-collections/release-notes/11.2/topic-57399.html > > > "New MX5, MX10, and MX40 3D Universal Edge Routers—Three new routers > based on the modular MX80 chassis are available in Junos OS Release 11.2R6." > > > Though in 11.4 relnotes it's 11.2R3 :-/ So you probably should try > 11.2R6. > > > > > > On 22.03.2012 11:16, Timh Bergström wrote: >> >> Hi, >> >> I recently bought a MX5-T (Instead of the MX80-5G) and I'm running >> 10.4R8.5 on my other MX80s and would naturally like to run the same >> codebase on all my MX-series hardware.
